Question: A simple pendulum is immersed in viscous fluid so that there is a resisting force of magnitude ca acting on the bob, where c is the coefficient of viscous damping, L the length of the pendulum and 0 the angular displacement. In the case in which the mass of the bob has the value In =1 kg and the length is L =1m the period of small-amplitude oscillations was observed to be T = 2.02 s. Determine the damping coefficient c.
